My impression of the game is good. I like the idea of this game. One thing that is interesting is about the light. If you turn off the flashlight you are totally blind and can not see anything.
I belive the game could become popular. And is good since there is also a lore involved in the game in which there was a fire incident where parents died and the child was not found. If more popular youtubers will play it, it will have success.
My recommandations: try to change the sound of the Mask jumpscare, it is somehow an ear rape which some people would find it annoying later. Also, remove the slapping sound or at least change it with something else so people would not find a reason to say "ohh, this is like baldi's basics!!!"
In other news, I also created a video with all the jumpscares from this demo version and a few other things included on the video like the map and my first gameplay
